Here's my advice. Call around to some law firms that specialize in disability claims. The nationwide firms that advertise on TV are just fine. See what they think about your chances of getting approved. Even if you decide not to use a law firm, their feedback can help you see how realistic you are being in thinking you might get your claim approved. If the lawyers are eager to represent you, that means you've got a pretty strong case. I would, then, turn it over to a law firm. That's what I did, and I got approved in 3 months. (Which meant I paid the law firm nothing, since my claim was not backdated.)

There are a lot of ways you can foul things up for yourself, by doing it yourself - as I think you are learning.

If the law firms are not too interested in taking on your case, then your case is probably kind of weak. Two things are against you: You are very young, and you are obviously well-educated. The SSA will tend to think that, with treatment and the passage of time, you could make yourself employable. They don't really care what your diagnosis is. They want to know: How does that make you unable to work? They will figure that you obviously got through school alright, so the ability to do that suggests you could hold down a job. But you might be able to make a good argument against that. Watch some videos on youTube of lawyers explaining how it works.
